切削加工时的切削速度、进给量或进给速度以及切削深度是表示切削加工过程的效率参数,其乘积即单位时间内机床所切除的材料体积。要提高生产率,缩短加工循环时间,其有效途径之一便是提高切削速度及进给量。另外,高速或超高速切削还具有以下优点: (1)减小工件在切削过程中产生热变形的可能 The cutting speed, feed rate or feed rate and depth of cut during cutting are the efficiency parameters that indicate the cutting process. The product is the volume of material removed by the machine per unit time. To improve productivity and shorten the processing cycle time, one of the effective ways is to improve the cutting speed and feed rate. In addition, high-speed or ultra-high-speed cutting also has the following advantages: (1) to reduce the possibility of workpiece in the cutting process of thermal deformation may
